Tokio, 32, who has talked about “turning his life around” with music after witnessing the horror stabbing of his school headteacher, admitted he was shocked as he was sent through ahead of power vocalist Sarah, 16.

He told Lorraine show host Rochelle Humes: “When there was me and Sarah, I thought she would be the one to go through.

Tokio has previously revealed music kept him out of trouble in his teenage years

Ahead of securing his spot in the final, Tokio exclusively told The Sun his pal Amy Winehouse gave him the confidence to make it as a musician.

Meanwhile on a previous episode of Good Morning Britain, host Ranvir Singh referred to a “tragic time” during his schooldays which saw his headmaster and dad-of-four Philip Lawrence collapse after he was knifed at the school gates.

Mr Lawrence, 48, died of a single stab wound at St George’s School in Maida Vale, West London, in 1995.

Tokio, who was just 11 when he witnessed the attack, admitted: “There was a tragic time.

“It’s something I don’t wish to talk about too much, because I don’t want to bring it back too much for the family.

“But I had music to really channel my energy and stay on a positive path.

“I’ve worked and worked and worked so hard to get to this point.

“I feel very, very lucky to be in a position to have turned my life around, and hopefully have inspired people who are going through the same things that I’ve been though that we are here together and we can do this.”
